The Aspire Tigon Kit comes in two sizes, A non TPD 24.5 mm version with a 3.5ml capacity tank and a 23mm 2ml capacity TPD version. The battery capacity of the 24.5mm Tigon kit is 2600 mAh and the 23mm TPD option of the Tigon kit has a battery capacity of 1800mAh. More than enough to keep you going throughout the day under normal use.

Filling couldn't be simpler in a child proof/leak proof tank of this type. First pull up on the top cap, then with your thumb or finger on the marker, slide open the top cap to reveal the silicon leak proof seal of the fill port. The silicon fill port on the TPD version tank has a self-sealing valve into which you can insert your chosen filling bottle nozzle to fill the tank. Closing the tank is the opposite, slide the top cap back into place covering the silicon seal and push down.
Remember, when using a new coil, to let the cotton of the coil saturate in the e-liquid for 5 minutes or so before you start to vape. This will ensure that you don't get dry hits or damage the coil.

On the Aspire Tigon tank, coil replacement is just a case of unscrewing the base hardware, pulling out the old coil and replacing with a new one. Then screwing the base hardware back on again. Note that the Tigon tank can still hold e-liquid when changing the coil, this is because the wicking holes in the tank are covered by a spring loaded sleeve that will slide shut sealing the holes when the coil is removed.
Remember, before using a coil for the first time to let it stand for 5 minutes after filling with e-liquid to saturate the coil and avoid dry hit and damage to the coil.

When removing and/or replacing the glass tube on the childproof TPD version of the tank, you need to follow these steps. First, unscrew and remove the base hardware and pull out the coil. Then invert the tank and using the special key provided, unlock the top hardware by placing it in the slot of the screw holding the top hardware (see diagram). Next, remove the glass tube. Replace the glass tube and follow the steps in reverse, (it is easier to place the screw onto the key first to locate it into the top hardware), secure the screw, insert the coil and replace the base hardware.
Remember, before using a coil for the first time to let it stand for 5 minutes after filling with e-liquid to saturate the coil and avoid dry hit and damage to the coil.

The first Aspire product to use an ingenious design that will seal the wicking holes in the tank when the coil is removed.
